DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIGS. 1 through 5 thereof, a new road speed control system embodying the principles and concepts of the present invention will be described.

As best illustrated in FIGS. 1 through 5, the road speed control system generally comprises roadside transmitter/receiver members 11 being adapted to be conventionally erected along roadsides where speed limits on roads 24 change. Each of the roadside transmitter/receiver members 11 emits a radio wave signal 12 upon a road 24. The radio wave signal indicates a maximum speed for that particular road 24. Each of the roadside transmitter/receiver members 11 is adapted to direct a respective radio wave signal 12 upon a portion of the road 24 where the speed limit changes depending upon direction of the vehicle 22. Each of the roadside transmitter/receiver members 11 is adapted to receive wave signals as to a speed of the vehicle 22.

A vehicle speed control assembly being adapted to be disposed in a vehicle 22 includes a microprocessor unit 15 being adapted to be conventionally disposed in the vehicle 22, and also includes a front receiver unit 13 being connected with wires 18 to the microprocessor unit 15 and being adapted to be disposed in a front portion of the vehicle 22, and further includes a rear receiver unit 14 being conventionally connected with wires 18 to the microprocessor unit 15 and being adapted to be conventionally disposed in a rear portion of the vehicle 22, and also includes a road speed sensor 16 being connected with wires 18 to the microprocessor unit 15 and being adapted to identify the speed of the vehicle 22 upon the road 24, and further includes a throttle control module 17 being connected with wires 18 to the microprocessor unit 15 and being adapted to be conventionally connected to an engine throttle. The front and rear receiver units 13,14 are adapted to receive the radio wave signals 12 being transmitted by the roadside transmitter members 11 and being adapted to transform the radio wave signals 12 into information readable by the microprocessor unit 15. The microprocessor unit 15 is adapted to receive information as to the speed of the vehicle 22 upon the road 24 from the road speed sensor 16 and to receive the information from the front and rear receiver units 13,14 as to the speed limit for that road 24. The microprocessor unit 15 is adapted to compare the road speed information with the speed limit information and to actuate the throttle control module 17 when the road speed is greater than the speed limit. Upon activation by the microprocessor unit 15, the throttle control module 17 is adapted to slow the engine down in accordance to the identified speed limit.

A monitoring and transmitting assembly for police includes a computer 21 being adapted to be conventionally disposed in a police car 23, and also includes a transmitter device 19 and a receiver device 20. The transmitter device 19 is adapted to transmit a signal to the front and rear receiver units 13,14 to bring the vehicle 22 to a complete stop. The receiver device 20 is adapted to receive signals from the road transmitter/receiver members 11 as to the speed of the vehicle 22.

In use, signals 12 are detected by the front and rear receiver units 13,14 from the roadside transmitting/receiving members 11 as to speed limit, and the speed of the vehicle 22 is detected by the road speed sensor 16. The speed limit and the road speed of the vehicle 22 is compared by the microprocessor unit 15, and upon the road speed being greater than the speed limit, the speed of the vehicle 22 is reduced by the throttle control module 17 to that of the speed limit as identified by the signal.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
